Virtual Keyboard

A small program I wrote in C++ in order to demonstrate the following concept: <br /> <br />A user is standing in front of a web camera and scrolls the letters of a virtual keyboard by moving his head or hand or body to the appropriate direction. Then he/she selects the appropriate letter (atm using a key but I intend to change it and select letters by making a sound) and an X event is sent to the X-server. <br /> <br />This virtual keyboard was a good opportunity to familiarize myself with the concept of optical flow, learn how to use the Xlib, the posix threads and the unix pipes in order to synchronize the camera and the Xserver events.
